Suppose you had a city that needed 40 units of power, with an environmental impact less than 40. The power company has narrowed the choices down to Trash-To-Steam facilities (power=5, cost=30, impact=6 for each unit), Wind facilities (power=2, cost=10, impact=1 per unit), and Hydroelectric facilities (power=20, cost=160, impact=10 per unit). Please make a recommendation and justify it! How could future developments change the numbers given in this scenario?
